if statement - How to change a value in a column dependent on a grepl in R -

-

i change values in 1 column depending on match in grepl column in data.frame.

example of data.frame:

df shot    class     data_text shot1   missed     missed jumper shot2   made       made 3 point jumper shot3   made       made jumper

what have been trying:

df$shot_type <- as.vector(0) #create new variable  (i in 1:length(df)) { if(grepl("e jumper", df$data_text[i]))  { df$shot_type <- "jumper"  } else if(grepl("d jumper", df$data_text[i]))  { df$shot_type <- "jumper"  } else if(grepl("t jumper", df$data_text[i]))  { df$shot_type <- "three" } }

doing method each if statement overwrites last.

my current results:

df shot    class    data_text                 shot_type shot1   missed   missed jumper             3 shot2   made     made 3 point jumper   3 shot3   made     made jumper               3

what results like:

df shot    class    data_text                 shot_type shot1   missed   missed jumper             jumper shot2   made     made 3 point jumper   jumper shot3   made     made jumper               3

any appreciated. please let me know if further information needed.

how this:

df$shot_type <- ifelse(grepl('d jumper|t jumper', df$data_text), 'jumper',                        ifelse(grepl('e jumper', df$data_text), 'three', na))

produces output:

   shot  class               data_text shot_type 1 shot1 missed           missed jumper    jumper 2 shot2   made made 3 point jumper    jumper 3 shot3   made            made jumper      3

note: coded na columns don't match 3 patterns. can modify code suit need.
